Hey couple things with your spec. You need to drop improve judgement and pic up paragon of virtue, 1 min less on Wings CD is pretty huge for throughput, that talent needs 2 points. You need to glyph seal of insight and word of glory, not seal of truth and holy shock.

You need to use light of dawn ALOT more, I saw several of your logs where you didnt cast it for a whole fight. Same thing with holy shock, I dont see you using it at all, you need to do so to build holy power. Figths where you are stacked use holy radiance and light of dawn as much as possible, use crusader strike for instant/cheap holy power generation. Make sure you use Guardian during periods of high raid dmg, keep holy radiance going and wog/guardian splash the raid for maximum throughput.
